I wonder if ever, ever at all, someone will manage to capture the Cologne Cathedral (Kölner Dom) without some scaffolding somewhere.
Cologne is where I did languages in uni.
Walked past this cathedral every day on my way to the train station!

(I plan to go to Budapest one day! It is a must-see city, I think).

You don't have a tripod?
You handhold your nightphotos?
Cool - but they can then not become all clear, of course.

the problem was in the 2 first ones, as I already said, the zoom and ofcourse the handhold, as you already noticed.
in the 4th one.. yeah.. the towers seems that they are going to merge - I didn't have some correction lens back then, just a HP 735 camera.

I am not speaking of distortion.
I find that quite normal and don't mind it too much in photos such as your Photo 4 here myself.
I am speaking of the scaffold half-way up the left tower, which is used for their permanent and never-ending repair works on the sandstone ... seems like this cathedral is NEVER without a scaffold on it somewhere... And I do like the SKY that you captured along with the towers.

aaah, sorry, I was reading your comment in a hurry and having this in my mind... that's the way I understood it.
Yeah, that's right about the scaffold, but that's the way you will find Notre Dame too in all photos and many more....

two years ago I couldn't take any shoot on the parisian Opera because of the scaffold.
